Description

This event tracks the highest temperature recorded in Washington DC on a specific date in the future. The outcome depends entirely on official weather data from a designated source, reflecting seasonal climate conditions and potential weather patterns.

Kalshi

The event resolves based on the maximum temperature recorded in Washington DC on October 31, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within any of these specified ranges, the associated market resolves to Yes. All markets share identical secondary rules regarding data verification and error handling. Preliminary data may be subject to revision, and the exchange retains discretion to delay resolution for material errors. In cases of unavailable data by expiration, markets resolve to the last fair price determined by the exchange. The 'Final' status on The Weather Company's platform is informational only and does not override these resolution procedures.
